Acoustics
Sound absorption:
- High performance perforated Zodiak® Acoustical Ceiling are able to achieve Noise Reduction Coefficients (NRC) of 0.83,
Weight
Zodiak® tiles are reinforced by 2 methods at the same time, Chops of fiber-glass and an Alkali Resistant fiber-glass mesh (10x10mm) to guarantees excellent isolation, best resistance and less weight per square meter.
Sound Attenuation
- Tests have confirmed Sound Transmission Coefficients (STC) of 38 using proper partition head seals.
Biological
Zodiak® cares for quality of life. Its fabrication does not cause any pollution, it does not contain asbestos or toxic elements and its characteristics (fire resistance, free from chemicals, hygrometric regulator, acoustic absorption, etc.) are elements which ensure utmost comfort, health and security.
Zodiak® tiles will not support the growth of bacteria or other microorganisms.
Thermal
Thermal conductivity: 0.45 W/mK (K.value) passed ASTM C 518.
Optical
Light reflectance of finished tiles is estimated at 75 %
Lifespan
Under normal conditions, Zodiak® Acoustical Ceiling will not deteriorate and can last for the lifetime of the building.
Transport , handling & storage
Zodiak® Acoustical Ceiling is shrink-wrap supplied or packed in cardboard cartons. Cartons should be stacked in the vertical position only, never flat; the stack should be a maximum of 3 high. Similarly, tiles should be stacked vertically when waiting fixing.
Installation
- With a few exceptions, the tiles are designed for installation on a standard 24mm exposed metal T-grid.
- Grid Hanging centers depend on the weight of tiles used and will be specified by the grid manufacturer; the recommended dimension should be strictly followed.
Cutting
Tiles can be easily cut on site using a carpenter’s fine tooth saw; the tiles should be placed face up on a flat, clean surface for cutting.
Access
Lay – in tiles are easily removed at any time by simply lifting them out, thus providing excellent access to services etc. installed in the ceiling void.
Maintenance
Clean the Zodiak® Acoustical Ceiling with a slightly damp cloth or, tiles can even be washed in a bath using a mild detergent solution.
